The config RANDOMIZE_SLAB does not exist, the authors probably intended to
refer to the config RANDOMIZE_BASE, which provides kernel address-space
randomization. They probably just confused SLAB with BASE (these two
four-letter words coincidentally share three common letters), as they also
point out the config SLAB_FREELIST_RANDOM as further randomization within
the same sentence.
Fix the reference of the config for kernel address-space randomization to
the config that provides that.

Most readers are probably going to figure out that the config is actually
all upper-case letters, as all Kconfig symbols are this way.
Properly capitalizing makes the script ./scripts/checkkconfigsymbols.py
happy, which otherwise would report this as a reference to a non-existing
Kconfig symbol.
So, use the right capitalization for the MAGIC_SYSRQ config in the kgdb
documentation.

i2c: validate user data in compat ioctl
On mt8195, the pinctrl node has pinctrl groups to group pin
configurations by users' need. In each pinctrl group, it has
subnode(s) to list pins needed and pin configurations. By supporting
multiple subnodes, we can configure different pin characteristics
(driving/pull-up/pull-down/etc.) in a pinctrl group.
Update pinctrl-mt8195.yaml to add subnode in pinctrl groups and an
example to illustrate the usage.

The link to the I2C specification is broken. Although
"https://www.nxp.com" hosts Rev 7 (2021) of this specification, it is
behind a login-wall. Thus, an additional link has been added (which
doesn't require a login) and the NXP official docs link has been

"Including fixes from.. Santa?
No regressions on our radar at this point. The igc problem fixed here
was the last one I was tracking but it was broken in previous
releases, anyway. Mostly driver fixes and a couple of largish SMC
fixes.
Current release - regressions:
- xsk: initialise xskb free_list_node, fixup for a -rc7 fix
Current release - new code bugs:
- mlx5: handful of minor fixes:
- use first online CPU instead of hard coded CPU
- fix some error handling paths in 'mlx5e_tc_add_fdb_flow()'
- fix skb memory leak when TC classifier action offloads are disabled
- fix memory leak with rules with internal OvS port
Previous releases - regressions:
- igc: do not enable crosstimestamping for i225-V models
Previous releases - always broken:
- udp: use datalen to cap ipv6 udp max gso segments
- fix use-after-free in tw_timer_handler due to early free of stats
- smc: fix kernel panic caused by race of smc_sock
- smc: don't send CDC/LLC message if link not ready, avoid timeouts
- sctp: use call_rcu to free endpoint, avoid UAF in sock diag
- bridge: mcast: add and enforce query interval minimum

2nd set of new device support etc for IIO in the 5.17 cycle.
A small additional set of things that just missed the previous
pull request and have mostly been through plenty of review before the
holiday period began (or are trivial). I've not taken some other series
on the list to allow for more eyes after the holiday period.
New device support
* adi,admv1013
- New driver for this wideband microwave upconverter including dt-bindings
and some device specific ABI due to the need to describe phase calibrations
of a differential channel on both i and q phases. Previously we could
do differential or i/q but not both on the same channel. The driver
ABI uses a workaround for core support which will do until we know if
this is a common requirement for which a more generic solution is
needed.
MAINTAINERS:
* Add Haibo Chen as a maintainer for various NXP SoC ADCs.
Minor cleanup:
* sunrise_co2
- Make sure an uninitialized value isn't used to set *val in read_raw().
Not a real bug, but a compiler or reviewer can't tell that based
on what they can see locally.
* tag 'iio-for-5.17b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio:

* dpu plane state cleanup in prep for multirect
* dpu debugfs cleanup (and moving things to atomic_print_state) in prep
for multirect
* dp support for sc7280
* struct_mutex removal
* include more GMU state in gpu devcore dumps
* add support for a506
* remove old eDP sub-driver (never was used in any upstream supported
devices and modern things with eDP will use DP sub-driver instead)
* debugfs to disable hw gpu hang detect for (igt tests)
* debugfs for dumping display hw state
* and the usual assortment of cleanup and bug fixes
There still seems to be a timing issue with dpu, showing up on sc7180
devices, after the bridge probe-order change. Ie. things work great if
loglevel is high enough (or enough debug options are enabled, etc).
We'll continue to debug this in the new year.
